[6pack] Subject: Re: Screw extraction

No Problem
You don't need them when _you_ bleed. It's in the station at the 
assembly line when they apply vacuum to the dry system to fill the brake 
fluid. It's not like bleeding the brakes in a shop or home.

I have done hundreds if not more cars manually with those screws or 
tinnerman nuts missing.
Don't sweat it. Just make sure the drum is on.
